Description:
- DC-DC boost converter kit
- HP300
- New and original
- 137mmX112mm
- China
- PCB and all components, power tube IRF2807, the output capacitor Sibi 5600UF 63V. Weight -frequency with oversized toroidal transformer , the board installed radiator .
- car amplifier and other battery powered appliances requiring booster
- HP300 power board to use an input voltage range, and the current output capacity must be large enough . There are three power
- input port +12 V CON and GND, +12 V which is connected to the input power supply
- Pole , GND connect the input power supply negative , CON pick a switch , and then connect to the positive power supply , power supply via the switch control board work .
- Special instructions board has several large resistance heating is relatively large, higher temperature , it is normal , that is the load resistance , fully working in a safe range , please do not worry about it , or suspicion.

Specification:
-Supply voltage : DC9-16V
- Output voltage : +-32V ( 12V input when )
- Rated Power : 500W
- Switching Frequency : 120KHz
- Efficiency: > 95%
- HP300 without protection and without a stable voltage function, the output voltage is fixed not adjustable , please note !
- HP300 power amplifier board with 500W output power, general power amplifier can also be used , as long as a suitable power supply voltage , and even Pure Class A power amplifier , you can use this board to drive . In addition, some IC amplifier
- Just like 3886 , 7294 and the like, to drive effortlessly . A power supply board can drive dozens of IC work .
- Amplifier suitable for supporting my store have A30 A50 MJ2001 and so on.
- HP300 boost circuit is developed specifically for car amplifier , the circuit is simple and easy to do , without having to adjust the circuit , mounted on components on the electrical connection can work , ideal for DIY.
- HP300 than the original version adds a pair of power tubes IRF2807, the output capacitor Sibi 5600UF 63V, golden yellow PCB, copper thickened to
- 2 ounces , even more noble luxury , and the price does not change !
- Meanwhile , HP300 power board performance is very excellent , the rated output power up to 500W, ordinary Power board simply can not be compared
.- High efficiency and stability , is also worth mentioning that , when the output power of 100W , the power switch and rectifier no heat ,radiators do not need to add , fully meet the general non- Class A power amplifier applications , enough to make you mad
- HP300 switching frequency of 120KHz, far more than the audio signal frequencies minimizes distortion and modulation between the so-called digital sound, the sound is more conducive to the reduction without distortion .
- Alternatively, the output voltage is not regulation.
